Item Description

EPDM Pre-Insulated Stainless Steel Tubing

by Duda Solar

EPDM Pre-Insulated tubing is very flexible and has the highest temperature tolerance and insulating factor of any pipe insulation on the market. It also has a protective layer on the outside of the insulation to prevent deterioration from weather and UV rays which come from the sun. It is available in single and twin rolls. Twin rolls are two tubes attached to each other and include a sensor wire for the collector sensor. The twin rolls offer the most convenience in installing a closed loop solar water heater.

Flexible Stainless steel tubing is a must have for any solar installation. It is highly resistant to corrosion and heat loss. Traditional copper piping loses heat 20 times faster than that of stainless steel tubing. Stainless steel has much lower heat conductivity, which results in higher efficiency for solar systems using stainless steel tubing due to less heat loss within the piping.

The greatest advantage to stainless steel tubing is it is flexible, so no additional fittings are required such as elbows to get from the solar tank to the collector on the roof. The one run of tubing saves trips to the hardware store and makes installations much faster due to no need for a torch and solder. Propylene glycol, commonly used in solar systems also causes problems with solder, so working on a piping system for a solar loop is no picnic with copper. Stainless steel tubing allows for a quick and easy removal with no need for any additional tools.

EPDM Pre-Insulated tubing is sold by 30 meter rolls only. It is designed to be weather and UV-ray resistant for outside applications. If you require a partial roll to complete a solar system, we recommend using cuts of our stainless tubing sold by the foot with our super 19mm nitrile insulation for the inside portions of your installation if you do not wish to use only part of a roll of the EPDM pre-insulated tubing.
